There are way more pages starting with A than listed there (E.g. ABBA, Apple).
Also affects empty queries, e.g. https://az.wikipedia.org/w/index.php?title=X%C3%BCsusi%3APrefixIndex&prefix=A&namespace=8 does not list Monobook.js but stops at Gadget-*.

Looks like it may be caused by rMW1483af0c894f: Cleanup Special:PrefixIndex::showPrefixChunk().
@Krinkle since this affects wmf.3 and .4 (I presume), I'd rather not rollback to .2 and instead just fix/backport. Reasonable?
@greg Yep, just making sure it's traceable as a regression from wmf.3 and UBN. This should be fixed or that commit reverted as soon as possible. This is causing users to make mistakes as it appears no further pages existed, and people may make decisions based on that (e.g. when fixing all pages in the MediaWiki namespace before flipping a switch or migrating some deprecated function).
